iPhone games: five of the best

In April I listed my 10 favourite iPhone games. The games on that list are still worth investigating but new titles are coming thick and fast. These are the ones that have been taking up my time over the last few months.

5. Racer (£0.59p)
This is incredibly simple and very addictive. Use your finger to navigate your speeding car down a crowded highway. If you crash – and you will – you'll lose a life. You'll need fast reactions if you're going to last.

4. iBomber (£1.79)
You have to fly a range of World War 2 bombing missions in this well-produced game. Tilt the iPhone to direct the plane and tap the screen to drop bombs. Each mission has specific objectives and the aim is to complete them without being shot down. Added complexity comes from a range of special bombs, each of which requires slightly different timing.

3. Westbang £0.59
Another very simple game, Westbang places you in the Wild West where you have to protect the bank from robbers. There are three doors in front of you and each time a door opens you could be greeted by a customer or a gunslinger. Tap the screen to shoot the bad guys and avoid killing the customers.

2. Civilization Revolution £2.99
It's almost 20 years old but this civilisation-building game is still a classic. The latest incarnation is every bit as involving as its predecessors and suffers very little in translation to the iPhone screen. The only danger with such a classic 'just-one-more-turn' title is that you may miss your stop if you play it on the train.

1. geoDefense £1.19
I said on the previous list that I'm a sucker for 'tower defence' games and this one is fantastic. It looks great – the retro graphics were inspired by the XBox Live title Geometry Wars – and it's fiendishly difficult. Instead of one long game taking place on one level, geoDefense treats each level almost as a puzzle. It took me months to finish them all but, tough though it is, the game keeps you coming back.

There's hours of fun to be had with the games on that list but what's surprising is that the whole lot will only cost you a little more than £7. If you're still stuck for games to play after that lot, try this list from the Telegraph's Tom Hoggins.
